Abstract
The invention discloses a pulsed detection threshold computation module, comprising a noise decorrelation module, a noise direct current elimination module, a noise wild value elimination module, a noise mean square root module, a pulsed preprocessing module, a pulsed elimination module, a noise mean value module and a threshold output module which are connected in sequence, wherein a video pulsesignal with noise is respectively input to the noise decorrelation module, the noise direct current elimination module, the pulsed preprocessing module and the pulsed elimination module; the noise decorrelation module, the noise direct current removing module, the noise wild value elimination module and the noise mean square root module are connected in sequence; the noise mean square root moduleis respectively output to the noise wild value elimination module, the pulsed elimination module and the threshold output module; and the pulsed preprocessing module, the pulsed elimination module, the noise mean value module and the threshold output module are connected in sequence. The pulsed detection threshold computation module of the invention can calculate characteristic value mean value and variance at real time, dynamically and high precisely, acquires pulsed detection optimum threshold according to preset false-alarm demand to realize optimum interception of the pulsed signal, and is convenient to be realized in programmable devices.
